RFR: JDK-8147634 - Need a JImage API that given a JImageLocationRef returns class name

[Jim Laskey (Oracle)]

Not reliably.  I can do a range check but I can’t test that the offset is correct (preceeding zero byte isn’t sufficient.)  The alternative is to switch to using indices instead of offsets for JImageLocationRef (as I mentioned should have ben done.)  Take a bit of fiddling at this point, but doable.  One would assume that you would guarantee on the result (shut down the vm), since that would mean a fail of the verification data (same as if jimage were invalid.)
